Benefits of technology

The present invention is related to a card connector that can be easily inserted and removed from a waterproof electronic device. The card connector includes a housing with a tray insertion portion and a plurality of contacts arranged within the tray insertion portion. A front cover portion at a front end portion of the card tray fits in a casing opening portion of the electronic device and seals the gap between the inner surface of the casing opening portion and the outer surface of the front cover portion using a cover water-sealing member. The front cover portion is movable relative to the tray main body to pull out the card tray using the front cover portion as a finger holding part. The connector also includes an ejector that moves with the card tray, a push-out spring, a heart cam, a loop-shaped pin guide groove, and a lock pin that allows the card tray to be easily inserted and removed from the housing of the electronic device.

Problems solved by technology

In such a tray type card connector, when the front cover portion of the card tray fits in the casing opening portion, the card tray cannot be easily ejected.
Since the pin insertion hole passes through internally and externally of the casing of the electronic device, there is a problem that the card connector is not compatible with waterproof devices.

first embodiment

[0037]Next, a tray type card connector 1 according to the present invention will be described based on an implementation example shown in FIGS. 1 to 6.

[0038]Note that in the drawings reference sign A indicates an electronic device such as a mobile phone or a smartphone, and reference sign B indicates a card such as an IC card. Note also that in the present implementation example a description is made with the front side in a card tray insertion and removal direction being “front” and the back side being “rear”.

[0039]The electronic device A is structured such that the tray type card connector 1 is used for connection of the card B such as an IC card, and by inserting and removing a card tray 2 into / from the electronic device A through a casing opening portion Aa opened at a lateral surface portion of a casing of the electronic device A, the card B can be mounted and demounted on / from a housing 3 disposed in the electronic device A, and the casing opening portion Aa can be closed by a...

second embodiment

[0071]Next, a tray type card connector according to the present invention will be described based on an implementation example shown in FIGS. 7 to 10A and 10B. Note that a description is made denoting the same components as those of the above-described implementation example by the same reference signs, and reference sign A indicates an electronic device and reference sign B indicates a card.

[0072]This tray type card connector 50 includes a card tray 51 where the card B is held; a housing 53 having a tray insertion portion 52 into which the card tray 51 is inserted; and a plurality of contacts 54, 54 . . . arranged in the housing 53 so as to project within the tray insertion portion 52. By inserting the card tray 51 into the housing 53 through a casing opening portion Aa, pad portions b1, b1 . . . of the card B held in the card tray 51 come into contact with the corresponding contacts 54, 54 . . . , by which the card B is electrically connected to a substrate having the card connect...
